Photo gallery changes

The old photo gallery script I wrote is going to be retired.

This new site system doesn't have such a facility; instead, I'll be using a program that came with my digital camera to create gallery pages, and then paste them into this system.

This costs me a little bit of flexibility-- there will no longer be a possibility to search for individual photos according to various criteria in the database; but it should allow me to put photos on the site much more quickly than the old one at a time method. In addition, the program makes all the thumbnails automatically, something I used to have to do by hand.
